The housing 110 may protect functional components of the leakage alarm module 100, and the charging member 120 may electrically connect the leakage alarm module 100 to a corresponding location, such as to the circuit breaker 200. The insulation protection device 130 can insulate the charged component 120, reduce the possibility of personnel touching the charged component 120 by mistake, and improve the safety. The receiving cavity of the housing 110 may receive the leakage alarm component of the leakage alarm module 100. The wiring structure 114 may mount and place the charging member 120, with a portion of the charging member 120 being specifically mounted within the connection groove 115. The live component 120, after being connected to the wire structure 140, may electrically connect the leakage alarm module 100 to a corresponding leakage alarm circuit. The insulation guard 130 may simultaneously insulate all of the connection slots 115. Specifically, the charging member 120 can be enclosed in the connecting groove 115, so that the possibility that a person touches the charging member 120 is reduced. The avoidance holes 1321 can facilitate connection of the wire structure 140, and generally, the wire structure 140 is provided with an insulating layer, and the protection effect of the insulation protection device 130 is not affected by the arrangement of the avoidance holes 1321.

The circuit breaker 200 of the present application may be a cabinet type circuit breaker, and the circuit breaker unit may be a molded case circuit breaker. The circuit breaker 200 may be generally installed in a corresponding cabinet, the cabinet door 300 of the cabinet may be provided with an operation hole, and the control structure of the circuit breaker 200 may be partially extended from the operation hole to facilitate a later operation. After the protection of the insulation protection device 130, even if the cabinet door 300 is opened, the electric shock of the user at the position of the leakage alarm module 100 can be prevented, and the safety of the circuit breaker 200 is improved.
